Question

What is the law of variation of the period T of a simple pendulum

Answer 1

The period of a simple pendulum is given by:

`T=2 \pi \sqrt{ (L)/(g) }`
where L is the length of the pendulum and
`g=9.81 m/s^2` is the gravitational acceleration. As we can see, the period of a simple pendulum depends only on its length.
